Replace strings that starts with a char and ends with space-CodePudding

I have trouble putting quotes to strings with the char @ and ends with the space, for example:

mystring = "@id string,@type string,account struct<@id string,@type string,accountId:string>"
mystring_expected = "`@id` string,`@type` string,account struct<`@id` string,`@type` string,accountId:string>"

How can I do it in Python?

CodePudding user response：

Just use a regex to match @ and one or more word characters, then wrap that with `

import re

mystring = "@id string,@type string,account struct<@id string,@type string,accountId:string>"
new_mystring = re.sub(r"(@\w )", r"`\1`", mystring)


mystring_expected = "`@id` string,`@type` string,account struct<`@id` string,`@type` string,accountId:string>"
print(new_mystring == mystring_expected)

CodePudding user response：

you could use a regular expression to find the words and put quotes using the re.sub function:


mystring = "@id string,@type string,account struct<@id string,@type string,accountId:string>"

pattern = r"(@\w \b)"
mystring_expected = re.sub(pattern, r"`\1`", mystring)
print(mystring_expected)
